i have a char array in a C app that i have to split into parts of 250 so i can send it along to another application that doesn't accept more at one time, how would i do that ? Platform: win32. Thanks in advance!

Hi all..
Was reading up a bit on my C++, and found this article about RTTI (Runtime Type Identification):
http://msdn.microsoft.com/en-us/library/70ky2y6k(VS.80).aspx . Well, that's another subject :) - However, I stumbled upon a weird saying in the type_info-class, namely about the ::name-method. It says: "The type_info::name member fu...

Hi,
This is a silly question but why does a Boolean take up 4 bytes and a char take up 2 in the .NET framework?
It makes me wonder if I should start using chars like a boolean to save memory in large apps.
...

So I have a char in c#:
char foo = '2';
Now I want to get the 2 into an int. I find that Convert.ToInt32 returns the actual decimal value of the char and not the number 2. The following will work:
int bar = Convert.ToInt32(new string(foo, 1));
int.parse only works on strings as well.
Is there no native function in C# to go fro...

Hi, if I have a range of say 000080-0007FF
and I want to see if a char containing hex is within that range, how can I do this? Thanks a lot.
Example
char t = 0xd790;
if (t is within range of 000080-0007FF) // true
Thanks

I have an application where I accept a socket connection from a telnet client and put up a simple, keyboard driven character GUI.
The telnet client, at least on Linux, defaults into line-at-a-time mode, so I always have to do ^]mode char manually.
A skim of the relevant RFCs suggests that if my application simply sent the characters IA...

This line:
strcat(query,*it);
(where *it is an iterator to a string)
Keeps giving me this error:
no matching function for call to \`strcat(char[200], const std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)'
I guess it's because strcat takes in a char* while *it is a string.
How do I convert it from a str...

Okay i am working on someone elses code. They do alot of this:
char description[256];
description[0]=0;
I know this would put a \0 in the first spot of the character array. But is this even a safe way to erase a string?
Also visual studio keeps reporting memory leaks, and i've pretty much tied this done to the strings that are used.

I am trying to map a virtual keycode to a char.
My code uses ProcessCmdKey to listen to WM_KEYDOWN which gives me access to the key pressed. For example, when I press single quote I get a key of 222 which I want to have it mapped to keychar 39 which represents... you guessed it... single quote.
My dev context is:
- .net Framework 2.0

Why does the SQLite C/C++ API return unsigned char *s for text values as opposed to the more de-facto char * type?
This is somewhat related to the unsigned char question, except that the SQLite API's decision seems opposite of the conventional char * advice given for string-like values.
For example:
const unsigned char *sqlite3_column...

Hi, I have a problem with the following code:
for(i = 0;(i - 1)< n;i++)
{
char* b;
sprintf(b, "%d", i);
}
It compiles fine but when I run it it give me the infamous "0XC0000005 Access Violation" error. I have tried setting b to NULL, "", "0", 0 and a bunch of other stuff but then I get the "0XC0000005 Access Violation" error or "Expre...

I have a legacy Oracle database that has multiple 1:n lookup tables that are based on CHAR(6) primary keys in the child tables. Unfortunately, I'm not the only one who has problems with how NHibernate deals with char fields (especially with those as primary keys). See:

I'm trying to make a database and so far, I've been using strings to store my entries from a text file into an array, but this just isn't working out. Thus, I began thinking of a new way of doing it.
What I want to do:
Lets say I have a text file with the following database...
